        computers at remote locations which are operated by others and to 
        provide access to Internet.

1.4     "POP" shall mean a Network point-of-presence where PSINet equipment 
        will be located and these POPs will be positioned throughout the world
        in order to permit authorized users to access the Network by telephone.

1.5     "PSINET CUSTOMER" will be EarthLink's non-dedicated 
        (non-static-addressed) or non-LAN dial-up customers designated by
        EarthLink as having their principal dial-up access through PSINet's
        dial-up network in the U.S. and Canada.

1.6     "NON-PSINET CUSTOMER" will be EarthLink's dial-up customers 
        designated by EarthLink as having their principal dial-up access
        through another network than PSINet's, whether it be EarthLink's own
        network, or another of EarthLink's network vendors.

1.7     "CUSTOMER" will be a customer of EarthLink, whether a "PSINet 
        Customer" or "Non-PSINet Customer".

2.      INTERNET CONNECTION SERVICES.

2.1     GENERAL. PSINet agrees to provide Purchaser with dialup (also call 
        "switched") telephone connection services for Purchaser's Customers to
        access the Network and the Internet. Purchaser and its Customers may
        access the Network from any PSINet POP in the United States and Canada.
        The fees to be paid by Purchaser to PSINet for such access services are
        set forth in Section 5.1.

2.2     PROVISION OF ACCESS. Throughout the term of this Agreement, PSINet
        shall provide Purchaser's Customers with the right to access at 
        speeds up to 128 Kbps using standard telephone and ISDN lines, and 
        use its Network at the levels then provided and supported by PSINet
        ("Access"). A recent estimated listing of Network POPs can be retrieved
        by sending electronic mail at 'pop-info@psi.com' or through access to 
        PSINet's world-wide web site at 'http://www.psi.net'. PSINet reserves 
        the right to install new POPs and/or to close existing POPs as it, in 
        its sole discretion, deems appropriate. In the event PSINet deems it 
        necessary to close an existing POP, PSINet shall provide Purchaser with
        sixty (60) days written notice thereof. Purchaser may order such Access
        on behalf of its present or future Customers and there shall be no 
        limit on the number of Customers who may use the Network; provided, 
        however, subject to the Service Level Agreement in Section 3.7 that 
        PSINet may refuse service to Purchaser because there is insufficient 
        capacity on the Network or in the POP to provide the Access amount 
        requested.

2.2.1   TERMINATION OF ACCESS. PSINet shall terminate the Access rights of 
        any Purchaser Customer as soon as is reasonably practicable upon written
        notice from Purchaser to do so or upon mutually agreed upon electronic
        process with receipt confirmed, but shall have no liability in
        connection therewith.

2.2.2   ISDN SERVICE. PSINet shall make ISDN 64k and 128k Internet connection 
        services available to Purchaser for Purchaser's dial-up customers. The
        fees to be paid by Purchaser for such services are set forth in Section
        5.1.

3.      PURCHASER OBLIGATIONS.

3.1     PURCHASER RESPONSIBILITY FOR ITS CUSTOMERS. Purchaser shall be 
        responsible for all Customer support, pricing and service plans, billing
        and collections with respect to its own Customers.

3.2     PURCHASER CONNECTION TO THE NETWORK. Purchaser may provide, at its 
        own expense, the telecommunications circuit for its connection to the
        Network which shall run between the best suited PSINet POP (as
        determined by PSINet) and the Purchaser's operations center (which
        includes the local telephone company or Competitive Access Provider
        circuits). In addition, Purchaser may provide an estimate of the traffic
        it anticipates between Purchaser's network and PSINet's Network.

3.3     [INTENTIONALLY LEFT BLANK]

3.4     [INTENTIONALLY LEFT BLANK]

3.5     CUSTOMER EQUIPMENT. PSINet shall not be responsible for the 
        installation, operation or maintenance of any computer equipment or
        computer software programs used by any Purchaser Customer.

3.6     OPTIONAL PEERING. In addition to the connection of Purchaser's 
        network and PSINet's Network as set forth in Section 3.2, Purchaser may,
        but shall not be obligated to, provide telecommunications circuits
        interconnecting Purchaser's network with PSINet's network at a location
        agreed upon by the parties and, from time to time, in other locations.
        The parties will use these circuits only for traffic originating within
        one party's network (or the networks of its Customers) and destined only
        to the other party's network (or the networks of its Customers).

3.7     SERVICE LEVEL AGREEMENT. Purchaser will maintain a 90 day rolling 
        forecast of predicted PSINet Customers at each POP, and provide this
        forecast to PSINet as requested. This forecast will include comparative
        historical numbers as they become available. Except as set forth in the
        section below, Purchaser will have no liability for the inaccuracy of
        this forecast.

        The number forecasted at each POP 60 days prior to a given day will 
        give rise to mutual obligations for that day at that POP as follows:

             1. If the number of actual PSINet Customers for a given POP on a 
                given day is greater than 110% of the number forecasted, no
                penalty or Service Level Agreement ("SLA") applies.

Network Access Agreement           Page: 3                               7/24/96


<PAGE>

             2. If the number of PSINet Customers on a given day is less than 
                90% of the number forecasted, Purchaser will pay a penalty of *%
                above the applicable fees for that POP for that day.

             3. For each POP where neither 1 nor 2 applies, PSINet will be 
                required to provide 99.5% availability for dial-in-access. For
                each day less than 99.5% availability is provided, Purchaser
                will be credited *** ********** ********* ***** ****** *** ****
                ****** ******** ******** ********* ******* ** **** ***. For
                example, if on April 2, 1997 Purchaser forecasted that there
                would be 910 PSINet Customers on the Smalltown POP, and the
                actual number of PSINet Customers on the Smalltown POP on 
                June 1, 1997 were 1000, and the total number of PSINet
                Customers on June 30, 1997 were 155,001, and the availability of
                Smalltown POP fell below 99.5% on June 1, 1997, Purchaser would
                be credited ***** * ******* ** ******* for that service lapse.

        Purchaser will provide at least 60 days' notice if it decides to 
        build a POP to service existing PSINet Customers in a particular city,
        provided the existing PSINet Customers for that POP exceed 5,000
        customers.

4.      PSINET OBLIGATIONS.

4.1     QUALITY OF SERVICE. PSINet shall provide to Purchaser (for its 
        Customers) Internet connection services that meet reasonable commercial
        standards, including, without limitation, with respect to accessibility,
        latency, packet loss, and throughput. For example, PSINet shall maintain
        throughput of 80% of nominal port speed (e.g. 23 Kbps for a 28.8 Kbps
        connection, 51 Kbps for a 64 Kbps single ISDN connection) 90% of the
        time. PSINet shall keep and maintain its Network in good condition and
        repair. The Network shall be properly maintained, serviced and upgraded
        by PSINet as it, in its sole discretion, shall determine is necessary in
        order to ensure connectivity to Purchaser Customers.

4.1.1   REPORTS AND INFORMATION REGARDING SERVICE.

4.1.1.1 ACCESS TO NETWORK MONITORING SYSTEMS. PSINet shall provide Purchaser 
        with read-only access to all applicable network monitoring systems used
        by PSINet to monitor its network. Such access will permit Purchaser to
        determine availability at each POP.

4.1.1.2 PSINET NETWORK OUTAGES. PSINet shall provide to Purchaser prompt 
        notification of any PSINet network outages that affect Purchaser's 
        Customers. When possible, at least three days advance notice of planned
        outages shall be given to Purchaser so that Purchaser's Customers may be
        alerted.

4.1.1.3 SNMP ACCESS. PSINet shall provide to Purchaser SNMP access to 
        PSINet's Network (i.e., direct read-only access to the dialup equipment,
        as well as, if

possible, the devices used to provide backbone transport) with respect to 
Purchaser's dial-up Customers, as soon as such access is practicable.

4.1.1.4  TECHNICAL INTERCONNECT. PSINet will develop a means to allow PSINet 
Customers to be authenticated via Purchaser's RADIUS serves in Purchaser's 
data center. PSINet Customers will be set up by Purchaser to log into 
PSINet's network with an "ELN/" in front of their username.

PSINet will provide real-time monitoring capabilities for Purchaser's 
technical and support staff to track access of PSINet Customers on PSINet's 
network. PSINet will provide 24X7 NOC-to-NOC support for Purchaser.

5.  PRICE AND PRICING TERMS.

5.1  CHARGES.  Purchaser will pay PSINet the applicable monthly fee for each 
PSINet Customer who has access to PSI's network during a particular month. 
Where the PSINet Customer did not have access for the entire month, the 
monthly fee will be prorated. Where the PSINet Customer has signed up AND 
canceled Purchaser's service within an initial 30 day period, no monthly fee 
will be due PSINet for that PSINet Customer.

In addition to PSINet Customers, Purchaser will have customers who use 
Purchaser's own dial-up TCP/IP network or other networks provided by vendors 
other than PSINet. Purchaser will make reasonable efforts to ensure that it 
segregates customers to one network or another in a given billing month. 
However, for such Non-PSINet customers who access the PSINet network in a 
given month, PSINet will charge Purchaser $**** for each day such Non-PSINet 
customer accesses the PSINet network, but no more than the applicable flat 
monthly rate for each PSINet Customer.

For each PSINet customer in the United States, monthly charges to Purchaser 
shall be based upon the number of PSINet Customers, calculated at the end of 
each month, as follows:

      TIER       PRICE       VOLUME
       A         ******      0-10,000
       B         *****       10,001-125,000
       C         *****       125,001 +

For each PSINet Customer in Canada, the monthly charge to the Purchaser will 
be $**** more (U.S. dollars) than the price noted above. Canadian and US 
Customers will count together cumulatively for the purpose of determining 
Purchaser's pricing tier above.

The minimum volume required to maintain Tier C pricing shall increase 
according to the month from the period beginning April 30, 1997 until 
December 31, 1997, after which the minimum monthly volume necessary to 
maintain Tier C pricing shall remain at 250,000 Customers.

</TABLE>

The applicable base charges above are applied to all PSINet Customers 
irrespective of the rate that previously was applied to 
each group of Customers. That is, when the volume threshold for a certain 
tier is reached, Purchaser shall be entitled to the pricing for that tier for 
all PSINet Customers (e.g. at and below that tier volume).

ISDN Service:  Charges will be the same as above for ISDN 64K connection 
services. Charges will be twice the 64K rate for 128K service.

5.1.1  MOST FAVORED NATION.  PSINet commits that the pricing provided to 
Purchaser will be at least as low as for comparable volume levels and similar 
services as that provided any other PSINet customer.

5.2  ADJUSTMENTS TO BASE CHARGE.  When the number of PSINet Customers exceeds 
500,000, PSINet and purchaser will begin good faith negotiations on new 
pricing terms.

5.3  MINIMUM COMMITMENT: On January 1, 1997, Purchaser's minimum monthly 
commitment to PSINet shall become $******* per month for each month of 1997. 
This minimum commitment will expire on December 31, 1997.

5.4  TAXES. Purchaser shall be liable for and shall reimburse PSINet for all 
taxes and related charges however designated, imposed in connection with or 
arising from the provision of access to the PSINet network by Purchaser or 
its Customers. This clause is intended to cover "per-subscriber" or 
"per-byte" charges targeted at the Internet traffic of Purchaser or its 
customers. These taxes will not include the following:

         -Taxes on T1 or PRI local loop lines to PSINet POPs
         -Taxes on PSINet's equipment or facilities
         -Taxes on PSINet's dedicated data circuits

5.5  INVOICES. PSINet shall invoice Purchaser monthly in arrears for all 
charges under this Agreement. Except where inapplicable per Section 5.9, all 
invoices will be payable within (30) days of receipt of invoice. 
Delinquent payments are subject to a late payment charge at the annualized rate 
of prime plus four percent computed monthly (4%), or portion thereof, of the 
amount due (but not to exceed the maximum lawful rate). In the event 
Purchaser shall fail to pay PSINet any amount due under this Agreement for a 
period of forty (40) days, PSINet, in addition to charging applicable 
delinquency fees, may discontinue providing to Purchaser and its Customers 
upon seven (7) days' prior written notice to Purchaser. PSINet shall resume 
providing Access immediately upon receipt of 


* - Redacted Material subject to Confidential Treatment Application


                                      6


<PAGE>

such payment, and in such event Purchaser shall pay PSINet a reasonable 
reconnection fee. However, Purchaser shall not be deemed to be delinquent, 
nor may access be terminated, until Purchaser has exhausted the line of 
credit described in Section 5.9

5.6  CUSTOMER CHARGES.  Purchaser is solely responsible for establishing and 
collecting its Customer charges for services it offers its customers through 
the Network and for preparing and mailing invoices to its Customers. 
Purchaser is responsible for payment of the total amounts invoiced it by 
PSINet regardless of whether Purchaser is paid by its Customers.

5.7  MARKETING REFERRALS.  Until January 1, 1997, PSINet will provide 
Purchaser with the first opportunity to sell to all leads calling into PSINet 
inquiring about or seeking the purchase of non-dedicated, dial up Internet 
access. At Purchaser's discretion, such leads will be transferred 
telephonically directly to Purchaser's telemarketing group, where Purchaser 
will attempt to sell the lead a dial-up access account. Purchaser will pay 
PSINet a one-time bounty of $***** for each lead that signs up for services 
and remains a paying customer for more than 60 days. By 30 days after the end 
of each month, Purchaser shall provide PSINet an accounting of the number of 
leads received and the number successfully converted into sign-ups, along 
with payment of applicable bounties.

5.8  USAGE REPORTS.  PSINet will provide full usage reports at the end of 
each day. These reports shall include detailed accounting of each Purchaser 
network customer (PSINet Customer or Non-PSINet Customer) login to PSINet's 
network. Additionally, PSINet and Purchaser will work to set up a system 
whereby Purchaser can track usage (connects and disconnects) in real time.

5.9  ADDITIONAL CONSIDERATION.  In exchange for Purchaser issuing to PSINet 
the sum of 200,000 warrants to purchase the same number of shares of common 
stock of Purchaser (or the equivalent thereof to compensate for any changes 
in the capital structure of Purchaser between the time of grant and the time of
exercise by PSINet, with 4 years to exercise), the exercise price to be the fair
market value at the time of grant, PSINet will provide the following credit 
and rental facilities to Purchaser:

         1. A credit line for Purchaser's payables to PSINet hereunder 
according to these terms:

         - Up to $5,000,000
         - Accruing interest at prime plus 4% per annum
           Applied to payables beyond the 30 day payment term described above 
         - Balloon payment at the end of the initial term hereof

         2. A commitment to a rental facility for $5,000,000 of equipment 
(owned or leased by PSINet) for deployment in Purchaser's network. Such 
rental charges shall include all costs, such as service maintenance, and 
shall be for equipment agreed to in advance by the parties.

                   other network equipment. The maximum initial value of 
                   assets being rented shall not exceed $5,000,000 in value.

                   Rental agreement shall include Fair Market Value buyout 
                   provisions, a 3-year term and an effective rate of not

                   Monthly rental payments will be due beginning 30 days 
                   after funding of Purchaser's IPO, or February 1, 1997,
                   whichever is sooner.

        Terms of Purchaser's warrants shall include a term of 4 years; 
        will provide for appropriate adjustments to the exercise price 
        and number of shares which may be purchased in the event of stock 
        splits, dividends and the like. In addition, PSINet shall receive 
        registration rights in respect to the shares (the "Shares") issuable 
        upon the exercise of the Warrants as described in the attached 
        Exhibit "A". PSINet shall be entitled to receive financial 
        information regarding the Company for so long as PSINet holds the 
        Shares.

6.      TERM/EXTENSIONS/TERMINATION. The term of this Agreement shall be two 
        (2) years, commencing on August 1, 1996 and ending July 31, 1998, 
        and, unless either party notifies the other in writing not less than 
        one-hundred eighty (180) days prior to the end of the initial term or 
        any extension thereof, this Agreement shall be automatically renewed 
        annually thereafter for a period of one year. Notwithstanding the 
        foregoing, such termination notice shall not be given by either party
        prior to December 31, 1997.

        materially breached this Agreement and has failed to cure such breach 
        within thirty (30) days after receiving written notice of such 
        breach; provided, however, that this notice period shall not apply to 
        a termination by PSINet in accordance with the provisions of Section 
        5.5.

7.      WARRANTIES EXCLUDED. EXCEPT AS EXPRESSLY PROVIDED HEREIN, PSINet 
        MAKES NO WARRANTIES IN CONNECTION WITH ITS NETWORK OR THE PROVISION

        EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION THE WARRANTY OF 
        MERCHANTABILITY AND THE WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE

        THIS AGREEMENT, WHETHER IN AN ACTION ARISING OUT OF BREACH OF 
        CONTRACT, BREACH OF WARRANTY, DELAY, NEGLIGENCE, STRICT TORT 
        LIABILITY, PATENT MATTERS OR ANY OTHER THEORY. NO ACTION OR 
        PROCEEDING AGAINST EITHER PARTY MAY BE COMMENCED MORE THAN TWO YEARS 
        AFTER THE SERVICES ARE RENDERED. THIS CLAUSE SHALL SURVIVE FAILURE OF 
        AN EXCLUSIVE REMEDY. EITHER PARTY'S TOTAL LIABILITY FOR GROSS

9.      INDEMNIFICATION OF PSINET.  Purchaser shall indemnify and hold 
        harmless PSINet and PSINet's directors, officers, employees, agents 
        and advisors from and against any and all claims of other persons or 
        entities arising out of material, data, information or other content 
        transmitted by Purchaser Customers or other acts or omissions of 
        Purchaser and/or its Customers.

10.     CONFIDENTIAL INFORMATION.

10.1    Nondisclosure. If either party acquires Confidential Information of 
        the other, such receiving party shall maintain the confidentiality of 
        the disclosing party's Confidential Information shall use such 
        Confidential Information only for the purposes for which it is 
        furnished and shall not reproduce or copy it in whole or in part, 
        except for use as authorized in this Agreement. Confidential 
        Information shall mean all information of the disclosing party which 
        it treats as confidential or proprietary. Confidential Information 
        shall not include information which is or hereafter becomes generally 
        available to others without restriction or which is obtained by the 
        receiving party without violating the disclosing party's rights under 
        this Article 10 or any other obligation of confidentiality. The terms 
        and conditions of this Agreement shall constitute Confidential 
        Information. The provisions in the Bilateral Nondisclosure Agreement 
        executed between the parties on July 18, 1996 shall survive the 
        execution and termination of this Agreement for any reason.

10.2    Duration. With respect to all Confidential Information, the parties' 
        rights and obligations under this Article shall remain in full force 
        and effect following the termination of this Agreement.

10.3    Ownership. All materials and records which constitute Confidential 
        Information, other than service orders and copies of this Agreement, 
        shall be and remain the property of, and belong exclusively to, the 
        disclosing Party, and the receiving party agrees either to surrender 
        possession of and turn over or to destroy all such Confidential 
        Information which it may possess or control upon request of the 
        disclosing party or upon the termination of this Agreement.

10.4    Injunctive Relief. The parties acknowledge and agree that, in the 
        event of a breach or threatened breach by any party of any provision 
        of this Article 10, the other party will have no adequate remedy in 
        money or damages and, accordingly, shall be entitled to an injunction 
        against such breach. However, no specification in this Section of a 
        specific legal or equitable remedy shall be construed as a waiver or 
        prohibition against any other legal or equitable remedies in the 
        event of a breach of this Article of this Agreement.

10.5    Legal Obligation to Disclose. Each party shall be released from its 
        obligations under this Article 10 with respect to information which 
        such party is required to disclose to others pursuant to obligations 
        imposed by law, rule or regulation; provided, however, that prior to 
        any such required disclosure, if practicable, such party provides 
        written notice to and consults with the other party.

11.     MISCELLANEOUS.

11.1    Independent Parties/No Agency. The relationship of PSINet and 
        Purchaser shall be that of independent third parties. Except as 
        otherwise expressly provided in this Agreement, this Agreement does 
        not constitute either party as the agent or legal representative of 
        the other party and does not create a partnership or joint venture 
        between the parties. Except as otherwise expressly provided in this 
        Agreement, neither party shall have any authority to contract for or 
        bind any other party in any manner whatsoever. This Agreement confers 
        no rights of any kind upon any third party.

11.2    Force Majeure. PSINet shall not be liable for failure to fulfill its 
        obligations hereunder if such failure is due to causes beyond its 
        control, including, without limitation, acts of God, fire, 
        catastrophe, governmental prohibitions or regulations, viruses which 
        did not result from the acts or omissions of PSINet, its employees or 
        agents, national emergencies, insurrections, riots or wars, or 
        strikes, lockouts, work stoppages or other labor difficulties. The 
        time for any performance required hereunder shall be extended by the 
        delay incurred as a result of such act of force majeure, and PSINet 
        shall act with dilligence to correct such force majeure.

11.3    Delays or Omissions. No delay or omission to exercise any right, 
        power or remedy accruing to a party under this Agreement shall impair 
        any such right, power or remedy of such party nor shall it be 
        construed to be a waiver of any such breach or default, or an 
        acquiescence therein, or of or in any similar breach or default 
        thereafter occurring; nor shall any waiver of any single breach or 
        default be deemed a waiver of any other breach or default theretofore 
        or thereafter occurring.  Any waiver, permit, consent or approval of 
        any kind or character on the part of either party of any breach or 
        default under this Agreement, or any waiver on the part of either 
        party of any provisions or conditions of this Agreement must be made 
        in writing and shall be effective only to the extent specifically set 
        forth in such writing. All remedies, either under this Agreement or 
        by law or otherwise afforded to a party, shall be cumulative and not 
        alternative.

11.4  BENEFIT AND ASSIGNMENT. No party hereto shall assign this Agreement, in 
      whole or in part, whether by operation of law or otherwise, without the 
      prior written consent of the other party hereto (which consent shall not 
      be unreasonably delayed or withheld); and any purported assignment in 
      violation of the foregoing shall be void. This Agreement shall be 
      binding upon and shall inure to the benefit of the parties hereto and 
      their respective successors and assigns as permitted hereunder. No 
      person or entity other than the parties hereto is or shall be entitled 
      to bring any action to enforce any provision of this Agreement against 
      any of the parties hereto, and the covenants and agreements set forth

      enforceable only by, the parties hereto or their respective successors 
      and assigns as permitted hereunder.

      such further documents and instruments and obtain such consents, as may 
      be reasonably requested in order to fully effectuate the purposes, 
      terms and conditions of this Agreement. In addition, PSINet may, at 
      reasonable intervals and upon reasonable notice to Purchaser, either by 
      itself or by its outside audit firm, audit the relevant books, records 
      and electronic data of Purchaser to assure proper payments have been 
      made by Purchaser hereunder. PSINet shall bear the costs of each such 
      audit unless the results of such audit show that Purchaser has 
      underpaid PSINet by 5% or more, in which case the cost of such audit 
      and the following correctional audit shall be borne by Purchaser.
